Build spec: Model 3 Highland front CCB
| Component | Stock front brake | STOPFLEX front upgrade |
|---|---|---|
| Vehicle | Tesla Model 3 Highland | Tesla Model 3 Highland |
| Front caliper | Factory floating caliper | Alcon RC6 6-piston |
| Front rotor | Steel | STOPFLEX 400mm carbon ceramic |
| Front pad | OE compound | STOPFLEX low-dust pad matched to CCB |
| Wheel requirement | 18 / 19 / 20-inch | 20-inch minimum, clearance verified |
| Axle scope | Front and rear steel | Front carbon ceramic upgrade |
Before you buy: wheel clearance
This package runs a 400mm front rotor, so it needs 20-inch wheels. Stock 18-inch and 19-inch Model 3 wheels will not clear it. Check both the spoke face and the barrel before ordering, even if your wheel diameter looks big enough on paper.
What changes with carbon ceramic
| STOPFLEX feature | Why it matters on the Highland | What you notice |
|---|---|---|
| Low-dust pad + CCB rotor | Light Tesla wheels show dark steel-pad residue within a few drives. | Wheels stay clean far longer between washes. |
| Carbon ceramic rotor, ~half the weight of steel | The Highland chassis is quick on turn-in; rotor mass is unsprung and rotating weight. | Lighter nose feel, less thump over broken pavement. |
| No-rust rotor face | EVs lean on regen, so steel rotors sit unused and surface-rust fast. | No orange bloom after the car sits out in the rain. |
| Heat-stable friction (near 0.3μ around 900°C) | Repeated hard stops and long downhill grades cook steel setups. | Pedal stays firm and predictable when you lean on it. |
| Long street service life (about 250,000–300,000 km) | Many owners keep a Model 3 well past one battery cycle. | Far fewer rotor replacements over the life of the car. |
What gets better
- Much lower brake dust on light-finish wheels.
- Lower unsprung and rotational mass up front.
- No surface rust after rain or long parked stretches.
- Composed pedal feel during repeated hard stops.
- Premium crackle-texture ceramic finish behind the spokes.
What to confirm first
- Whether your car already runs Alcon RC6 or needs the full front conversion.
- That the rotor and pad ship as one matched CCB package, not a bare rotor swap.
- 20-inch wheel fitment at both the spoke face and the barrel.
- This is a front-axle carbon ceramic upgrade.

Tesla Model 3 Highland CCB FAQ
Can I keep my Alcon RC6 calipers and just switch to carbon ceramic rotors?
Often, yes. This style of upgrade keeps the Alcon RC6 caliper and swaps the steel rotor for a STOPFLEX carbon ceramic rotor assembly with matched pads. Confirm your exact hardware before ordering so the rotor and hat configuration lines up.
Do the 400mm rotors on a Model 3 Highland need 20-inch wheels?
Yes. The 400mm front package shown here requires 20-inch wheels. Stock 18-inch and 19-inch Model 3 wheels will not clear it, so check barrel and spoke-face clearance before you buy.
What do carbon ceramic brakes actually do for a street-driven Model 3 Highland?
The big wins are far less brake dust, roughly half the rotor weight of same-size steel, no rust, and long service life in normal street driving. It matters most if you want clean wheels and a more premium daily brake feel.
How long do STOPFLEX carbon ceramic rotors last on the street?
In normal street use, away from track abuse, STOPFLEX carbon ceramic rotors can reach roughly 250,000 to 300,000 km. Real-world life depends on how you drive, your pad choice, and overall use.
Will the rotors rust if my Model 3 sits outside in the rain?
No. Unlike steel, STOPFLEX carbon ceramic rotors don't rust after rain. That's a real perk for an EV that spends a lot of time parked and charging between drives.
